OVA
Description
Chihiro Uomi, nicknamed "Womi," is the Student Council President at Eiryou High School. She met the main characters through a school exchange program with Ōsai Academy, designed to share operational knowledge and improve both councils. This fostered an ongoing friendship, notably with Shino Amakusa, bonded by shared traits like a reserved exterior masking a penchant for perverted humor.

Her appearance is distinctive: black hair styled in twin tails, vacant deadpan eyes, and a notably large bust that often attracts attention and envy. She typically wears Eiryou High's uniform—a white blouse with a red necktie, light blue sweater, and dark blue skirt—though she donned a dark blue blazer bearing her school's emblem for a relative's wedding.

Uomi presents a calm, polite, and emotionally reserved demeanor, rarely raising her voice or losing composure. Yet, like Shino, she frequently employs sexual innuendos, delivered flatly in her deadpan manner which lessens their impact. She self-identifies as unsociable and emotionally distant, reflecting on her limited social life before high school. Despite this, she shows affection towards Suzu Hagimura, often hugging her upon meeting, though Suzu seems hesitant about these gestures.

She develops a significant romantic interest in Takatoshi Tsuda, openly pursuing him through actions like visiting his home, cooking for him, and suggesting marriage, prompting jealousy from Shino and Suzu. Their relationship deepened upon discovering a familial connection: her cousin married his cousin. Following this, she insisted he call her "Onee-chan" (big sister) while she called him "Taka-kun" and his sister Kotomi "Kotomi-chan." This connection enabled regular, comfortable visits to the Tsuda household, where she would shower and leave belongings, sometimes sparking concern or envy among others interested in Takatoshi.

Moments reveal vulnerability, like struggling with public speaking and occasionally adopting a childish greeting style contrasting her usual self. She holds a part-time job at a fast-food restaurant, shown in an OVA. Her vice president, Mori-san, often acts as her straight man ("tsukkomi") countering her deadpan remarks.

Her surname combines "fish" (魚) and "to see" (見). Her phone number (8008135) forms the numerical pun "BOOBIES." In one movie, she invited Takatoshi to "be with her," misinterpreted by Shino as a transfer request but later revealed as a marriage proposal. She also jokingly claimed her first name was "Christina" before confirming it as Chihiro.
